It is known, that at heating of paints at them viscosity decreases (i.e. They become more liquid) and, hence, necessity for them razbavlenii partially disappears, therefore at drawing by nitroenamel dispersion preliminary heat up to 55-60°С and by that reduce the expense of solvents on 20-30%; gliftalevye pentaftalevye, mochevino - and melaminoalkidnye enamels heat up to 70°С, reducing the expense of solvents ours of 30-40%.

A Paint coat, put in the warmed-up condition, thicker than a layer put in the usual way, therefore it is possible to reduce quantity of coat layers. So, on Gorki car factory instead of four layers of nitroenamel with viscosity 18 sek one layer of the warmed-up enamel with viscosity 26-30 sek and two layers with viscosity 18 seconds

Coverings, obrazuemye by hot dispersion, on quality do not concede to a covering received in the usual way. Hot dispersion it is possible to put nitroenamels, pentaftalevye, melaminoalkidnye, mochevinnye and phenolic enamels. Perhlorvinilovye enamels behind some exception for hot dispersion are not suitable.

To drawing of the warmed-up paint and varnish materials apply special devices. The basic knots of such devices are heaters of a paint of air, kraskoraspylitel, the pump and the electric motor. Nagretaja the paint in the course of work circulates between a heater and a spray that eliminates its overheat and facilitates washing of devices by solvent after work. Device management is carried out from the board which has been taken out separately.

The pistol consisting of actually spray and a heater is applied To drawing of the warmed-up varnishes and paints also. The Pistol-spray is suitable for performance of small volume of painting works.
